WPF Toolkit Datagrid Performance issue in rendering - WPF Discussion Boards

Hi,

I am trying to encrypt my appSettings section through code but i am facing some problem.

This is what is am doing
-- app.config

<? xml version="1.0" encoding="utf-8" ?>
<configuration>
  <appSettings>
    <add key="Encrypt" value="Encrpyted"/>
  </appSettings>
</configuration>

--Code

string s = System.IO.Directory.GetCurrentDirectory();

s = s + "\\Test_Encrypt_1_WPF.exe.config"; // "Test_Encrypt_1_WPF" is my exe name

Configuration config = ConfigurationManager.OpenExeConfiguration(s);

AppSettingsSection section = (AppSettingsSection)config.GetSection("AppSettings");

if (!section.SectionInformation.IsProtected)
{
     section.SectionInformation.ProtectSection("RsaProtectedConfigurationProvider");
}
config.Save(ConfigurationSaveMode.Modified);

In the above code the "section" object is showing null i.e. i am not able to find the "AppSettings" section.
I even tried configuration/appSettings but the same result.
Can anyone please help!

Thanks in advance,

Samar

Hi All,

I got the solution myself.

Instead of

string s = System.IO.Directory.GetCurrentDirectory();
s = s + "\\Test_Encrypt_1_WPF.exe.config"; // "Test_Encrypt_1_WPF" is my exe name
Configuration config = ConfigurationManager.OpenExeConfiguration(s);

i wrote

Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);

This worked!!

Regards,

Samar

There is already a way to do this, http://msdn.microsoft.com/en-us/library/system.configuration.sectioninformation.protectsection.aspx[^]

Hi Mark,

I was not able to find the link you have mentioned when i was searching.

The solution in the link looks pretty similar to what i have tried.

Please do let me know if i am incorrect in any way on stating the above.

It is the same, but at least you have an example that should work.

Hi All,

I am facing a performance issue with WPF Toolkit datagrid. In my application I have created a view containing multiple Data Grids (around 15) with about 100 rows in each grid. The view shows 15 rows for each grid. The grids are placed in an ListView, so when I scroll in the list view I am experiencing a performance hit.

Can anyone guide me to resolve the issue.

Thanks

I have no idea about the datagrid, but did you Virtualized your ListView?

e.g.

<ListView 
    VirtualizingStackPanel.IsVirtualizing="True"
    VirtualizingStackPanel.VirtualizationMode="Recycling"

Wrong forum mate.
Your question has nothing to do with Silverlight, right?

You would need to add C# code in your code behind file. This code should generate a button dynamically.
See here.

You may also try creating a UserControl and then use it for your application. I think, it will be useful and handy in your case.

Make game Missionaries and Cannibals by WPF

28-Apr-10 1:53

i've try it, but it can't. can you give me a sample. I would like create random button or image appear when it's loaded, and it's can change how many button or image appear in current time. Like the first button appear 2 buttons or images when loaded, and we click other button(outside of the buttons which created).. and than the next random button appear with different buttons (may be 3 buttons appear or 10 button).

I suggest you do some research around writing WPF applications, doing it well is pretty different from Winforms.

The other thing is, I'd look at the AI stuff first as it's the most difficult, you can always get to grips with WPF as you go along.

Don't just dive in, some of WPF is very different from previous technologies. I would suggest this excellent range of tutorials (which includes events)

Installed Silverlight 3 Tools, Getting Exception

Using SL3, VS2008 SP1, and .Net 3.5 SP1...

When I open a XAML file, I get the follwoing exception:

An unhandled exception occurred (System.TypeInitializationException) in PresentationFontCache.EXE [4716].

I googled the message, and there are no hits - at all. If I google the EXE cited in the message, I get a bunch of hits about people either wondering what the file is for, or asking if they have a virus.

Has anyone ever seen this, and even better, does anyone know how to fix it?

Well - for starters, this file is in the GAC, so is not a virus.
Not unless a virus got to it and destroyed it somehow.

WPF applications depend upon PresentationCore, PresentationFramework and WindowBase assemblies that need to be loaded and the start-up of the PresentationFontCache service. However, what this has to do with Silverlight is what I have no clue about.

Try to reset your devenv settings by using devenv /resetskippkgs in the VS command prompt.
Reinstalling SL3 may then be the only option (unfortunately).

I *know* it's not a virus. I was just mentioning what I found on google.

After I posted the original message, I found out both of the other guys on our team are getting the same error. I installed this stuff on my own personal machines (all running Windows 7 64bit), and it doesn't happen. I've only seen it on the machines at work (all running Vista 64bit). The only difference (that I can see) is the OS.
